| Outline of Final Research Achievements |
It has been well recognized that magnetic systems with triangular lattices shows the geometrical frustration effect, which destabilizes the simple Neel ground state and can lead to a new exotic ground state. This work aims at expanding the geometrical frustration concept into the areas of itinerant electron and superconducting systems, and discovering a new quantum state of matter such as exotic superconductivity. For this purpose, NMR and ac susceptibility measurements have been performed for several materials with frustrated lattices. The experimental results give strong indication for a possible triplet superconductivity in an organic system with a triangular lattice.
